Kernel Ressource update needed
Created by: thorian93
On my VPS running Ubuntu 14.04 LTS 64bit I had issues getting GitLab CE Omnibus to work.
I followed the instructions for my OS on https://about.gitlab.com/downloads/ and made the necessary changes for GitLab to work with Apache2. That far: No noticeable problems.
But when I tried to do a gitlab-ctl reconfigure I was not able to get the built-in postgresql server running.
After days of research and no helpful content online I identified two kernel parameters as the villains: kernel.shmmax and kernel.shmall.
As far as I can tell the problem is the following: The correct values for GitLab to work are set in /etc/sysctl.d/90-postgresql.conf but without a reboot the old values stay active. In my case my server provider had too small default values.
Maybe it is possible to have gitlab-ctl reconfigure update the kernel parameters with:
sysctl -w kernel.shmall=123456
sysctl -w kernel.shmmax=123456
This is my first issue so if I am missing important information or if I said too much please let me know.
